FIBER OPTICS VIDEO TRANSCEIVER TRAINER

BHI-ENE-2308
Qty Comments
TECHNICAL SPECIFICATIONS
This trainer comes with three components, namely, an SMA connectorised 850 nm FO LED, a matching PIN photodiode and an SMA-connectorised two -meter optical fiber G1/multimode fiber patchcord . Instruction manual describes the use of F.O cable and the Video Transceiver Module (VTM) (supplied as an optional necessary to Kit) to transmit and receive dideo signals via the optical fiber medium. This trainer is supplied as a fully assembled and tested, single-sided glass epoxy printed circuit board. To make the system operational an iternal regulated dual power supply +5 Vdc to + 9Vds is provided. VCR and an oscilloscope will be required to study the signals. Some components have been mounted to facilitate easy change, by the user to achieve desired performances. A bandwidth of 8 MHz is provided.

FIBER OPTICS VIDEO TRANSMITTER
The fiber optics video transmitter employs the direct intensity modulation method. The LED optical output is fairly linear over a region of the LED forward current. By employing current feedback operational amplifier, a large bandwidth linear current driver for the LED is realized, covering the full range of the video signal.

FIBER OPTICS VIDEO RECEIVER
The optical demodulator comprises a low-noise trans-impedance amplifier followed by a Wide band RF amplifier.

HOUSING : It is housed in an elegant fiber cabinet
DIMENSION : 27cms x 17cms x10cms
WEIGHT : ( Approx.) 500gms
POWER : 230VAC-Mains operated
